Angle Measures
Angle measure is the measure of the amount of rotation around a fixed point. It is expressed in degrees, minutes, and seconds.There are different types of angles:
- Acute angles are angles that measure less than 90 degrees.
- Right angles are angles that measure exactly 90 degrees.
- Obtuse angles are angles that measure more than 90 degrees but less than 180 degrees.
- Straight angles are angles that measure exactly 180 degrees.
- Reflex angles are angles that measure more than 180 degrees but less than 360 degrees.
- Full angles are angles that measure exactly 360 degrees.
Segment Lengths
Segment length is the distance between two points. It is expressed in units such as inches, centimeters, and meters.To measure the length of a segment, you can use a ruler or a measuring tape.There are different units used to measure segment lengths:
- Inches are used in the United States and some other countries.
- Centimeters are used in most other countries.
- Meters are used in the metric system.
Relationship between Angle Measures and Segment Lengths: Angle Measures And Segment Lengths Quick Check
There is a relationship between angle measures and segment lengths. The larger the angle measure, the longer the segment length. This relationship is used in many applications in geometry, such as finding the length of a side of a triangle or the area of a circle.

Clarifying Questions
What are the different types of angles?
Angles are classified into various types based on their measure: acute angles (less than 90 degrees), right angles (90 degrees), obtuse angles (between 90 and 180 degrees), and straight angles (180 degrees).
How do you measure the length of a segment?
To measure the length of a segment, a ruler or measuring tape is typically used. The measurement is expressed in appropriate units, such as inches, centimeters, or meters.
What is the relationship between angle measures and segment lengths?
In certain geometric figures, such as circles and triangles, there is a relationship between angle measures and segment lengths. For example, in a circle, the measure of an inscribed angle is half the measure of its intercepted arc.
